To find the relative frequency of people who use their car, you can use the formula for relative frequency:
\[ \text{Relative Frequency} = \frac{\text{Number of people using a car}}{\text{Total number of people surveyed}} \]
In this case:
- Number of people using a car = 35
- Total number of people surveyed = 92
Substituting these values into the formula gives:
\[ \text{Relative Frequency} = \frac{35}{92} \approx 0.3804 \]
To express this as a percentage or in decimal form up to two decimal places:
\[ 0.3804 \approx 0.38 \quad (\text{to two decimal places}) \]
Thus, the relative frequency of people who use their car is 0.38.
